Cadet Chapel, the landmark Gothic church that is a center for spiritual life at the US Military Academy at West Point, hosted its first same-sex wedding Saturday.

Penelope Gnesin and Brenda Sue Fulton, a West Point graduate, exchanged vows in the regal church in an afternoon ceremony, attended by about 250 guests and conducted by a senior Army chaplain.

The two have been together for 17 years. They had a civil commitment ceremony that didn’t carry any legal force in 1999 and had long hoped to formally tie the knot. The way was cleared last year, when New York legalized same-sex marriage and President Barack Obama lifted the “Don’t ask, don’t tell” policy prohibiting openly gay people from serving in the military.
